The Origin of Catalog or Catalogue
The word comes from the ancient Greek word katalogos, meaning “a list” or “register.”
It later entered Latin as catalogus and then French as catalogue. British English kept the French-style spelling with -gue.
When American English developed, many words became shorter and simpler. As a result, catalogue became catalog in the United States.
Today, both spellings remain correct because they developed from the same historical word.
